Whenever it rains (as it is now) the thought of a hygrometer comes to mind, as if I’d actually pay attention to the humidity levels. If you’re more committed to understanding weather pattens than I, perhaps you’d use a combination thermometer and hygrometer wall clock? It’s not water proof (pity), so do be careful about where you place it… perhaps a covered patio area or porch? There’s also a few variations in color and design (see below).
